The first prototype is complete and was tested on a few occasions. Most notably, the pack can not hold weight. I tried putting some weight into it and the shoulder straps ripped off. The fabric is too weak to hold anything of any substance. Therefore I was unable to test out any shoulder strap configurations. The general size and feel of it was favorable. But adding the weight is where I will really gather some good insight. I need another prototype. My sewing job was also pretty terrible while I figured out how to sew. I just used some crap I made up and now I am learning the right stitches to be using. It's easy too, just a simple felled seam. It will make my sewing job so much easier on the next go around.
I decided that I am going to go with a traditional bottom on the pack. The flat-bottomed piece that is thicker than the rest. It makes sense from a durability point of view but the bigger factor is the ease of sewing. My sewing is not that good and doing curved features is not my forte. It might be simple enough but there is no need to complicate things right now. I can add that feature in when I really need it.
